"The average speed of an express train is 14 miles per hour more than 1/3 the speed of a freight train"
___ e = (f / 3) + 14 ___ 2e = (2f / 3) + 28

"In two hours the express train travels the same distance as the freight rain in three hours
___ 2e = 3f

substituting ___ 3f = (2f / 3) + 28 ___ 9f = 2f + 84 ___ 7f = 84
